Full Opening Check Valves
Full Opening Check Valves
(OP)
Hello valve gurus,
Do you think Full opening check valves are supposed to be installed horizontally too?
Clearance between body and disc is very small for these valves compared to regular swing check valve.
Any little intolerance at the hinge pin joint will cause the disc to drop a little on the body.
Any of you came across such problem before?
Thanks in advance

RE: Full Opening Check Valves
You are going to have to give us more information about this "Full Opening Check Valve".
Most of us are familiar with the following
- Swing Check Valves
- Wafer(Single and Double Disc) Check Valves
- Ball Check Valves
- Piston Check Valves (also called Lift Check Valves)
But I have no idea what you mean by "Full Opening Check Valve"
RE: Full Opening Check Valves
It is piggable.
Even API 6D spec mentions this valve.

In my experience, swing check can be assembled in horizontal, preferrably spring assisted to check.

Your question could be put two ways:
1. Can I find a piggable, full opening check valve on the market, type swing check, to be mounted in a vertical pipeline, flow direction vertical upwards, stopping downward flow (where fluid is drinking water??? wastewater??? or other fluid???? etc must be specified)
The answer is yes.
2. Same question as above, but given a specific brand, type and size/pressureclass you already have in mind.
The answer is probably but the specific valve has to be allowed for this use by the factory. This might involve restrictions on type of inner surface of the valve related to type of pig, and require spring or outside weight and arm to close the valve.
